The top people where I work have MS or PhD degrees. They had BS degrees and the company saw their talent and paid for continuing education. The PhD people were given a pass upon hiring and have worked out. I can't think of anyone that came in with an MBA-ish degree that are worth a darn. They are weeded out quickly. I think you can get an MBA from a million places...

Are you currently or recently worked in the field that pertained to your field of study? Yes and No. My emphasis was International Business, but I don't do as much of that anymore. I own or have partnerships in a number of business entities - all domestic

Was it worth the time and money? Absolutely

Does having a post-grad degree prevent you from working on other fields?Not at all, it just emphasizes your work ethic and desire to work hard toward your goals.

Bottom Line: It's up to you what you do with it once you are out. The hard part is after you get your Masters.......
